From temporal variability to integrated metabolic balance: Interpreting total alkalinity and dissolved inorganic carbon relationships in dynamic coral reef ecosystems

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Linear regressions between total alkalinity (TA) and dissolved inorganic carbon (DIC) are widely used to infer the balance between net ecosystem calcification (NEC) and net ecosystem production (NEP) in coral reefs. Using high‐frequency carbonate chemistry observations from an Australian reef flat and simple numerical models, we show that TA ...

p- and m-Cresols emitted from estrous urine are reliable volatile chemical markers of ovulation in mares

, 2012
Urine samples from 14 mares, belonging to five breeds, were collected at estrus and diestrus to search for estrous specific volatile compounds which could be used to determine ovulation time.

Development of methods based on low-temperature partitioning (LTP) for monitoring cresols and chlorophenols in sewage sludge, soil, and water in column leaching

, 2023
Cresols and chlorophenols are chemical contaminants that are potentially toxic to humans and can be found in sewage sludge. These chemical contaminants can migrate into the sludge-soil-water system when sludge is used as a conditioner for agricultural ...

Effects of dietary crude protein level on odour from pig manure

Animal, 2007
The objective of this study was to determine the effects of dietary crude protein (CP) level on odour emission, odour intensity, hedonic tone, and ammonia emission from pig manure and on manure composition (pH, total nitrogen, ammonium, volatile fatty ...

Development and Evaluation of the Simplified Tropospheric Chemistry Mechanism T4 in the Community Earth System Model (CESM) for Climate Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Simulating atmospheric chemistry in Earth system models is critical for climate projections but remains computationally intensive. Comprehensive mechanisms, such as the MOZART‐T1 scheme in the Community Earth System Model (CESM), often limit the feasibility of long‐term or large‐ensemble simulations.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds
